A2G2 glycan (G2), procainamide labelled

A2G2 glycan (G2), procainamide labelled (A2G2 N-linked oligosaccharide, procainamide labelled; A2G (4) 2 glycan, procainamide labelled) is a polymeric N-glycoprotein that serves as a multifunctional fluorescent linker. The resulting conjugate, by emulating the antennae structures of N-glycans, exhibits high sensitivity and specificity.
